TONIGHT'S MIGHT-SEES

"Ghost Whisperer," 7 p.m., CBS. Last week, Melinda's husband was accidentally killed. We didn't like the plot — which absurdly had a cop shoot at an unidentified silhouette — or the result. Still, it's an ambitious effort to nudge the show into a new direction. Now we find Melinda grieving and doubting the value of her abilities. Meanwhile, she tries to help a teen ghost.

"Sanctuary," 8 p.m., Sci Fi. Ashley Magnus — young, smart and a fierce fighter — has known only the basics: Her mother Helen is 157 years old and has been around. What Ashley doesn't know is that the scary John Druitt is her father. She'll learn tonight. Meanwhile, her mom meets a transformed version of Nikola Tesla, the long-ago science genius. It's an interesting and pivotal episode.

OF NOTE

"Henry Rollins: Uncut from South Africa," 5:30 p.m., IFC (Oceanic Digital 675). Henry Rollins may be best known as a bad (but enthusiastic) rock singer. Here's a much more interesting side. Skipping the music, Rollins delivers clever talks on such subjects as Ted Nugent and Iggy Pop; he also offers taped portraits of black life in South Africa.

"The Wizard of Oz" (1939), 6 p.m., TBS. Here's a new chance to see a family classic.

"Everybody Hates Chris," 7 p.m., CW (Oceanic Digital 93). A new dilemma for Chris: Should he come forward as a witness when he wasn't supposed to be there?

"Whale Wars," 8 p.m., Animal Planet. First is a rerun of the opener. Paul Watson, a Green Peace founder now on his own, tries to confront a Japanese whaling ship; his inexperienced crew bungles things. Then comes a new episode: When members board the whaler, two are captured.

"Crusoe," 8 p.m., NBC. For a deserted island, this gets a lot of visitors. Crusoe faces a question: Should he focus on stealing the cannibals' boat or on rescuing their victims?

"Numb3rs," 8 and 9 p.m., CBS. First is a rerun, tracking a rapist cop. Then, in a new episode, Don and Charlie feel a friend's death wasn't suicide.
